@exa Cool thanks! :-)

@lupyuen if by "loop forever" you mean "the hart isn't going to execute past the WFI instruction", then yeah that code might be wrong
@icenowy Yep thanks! I just realised that Linux Boot Code uses WFI + Loop together: https://github.com/torvalds/linux/blob/f6cef5f8c37f58a3bc95b3754c3ae98e086631ca/arch/riscv/kernel/head.S#L185-L188
@exa I have some code that assumes WFI will loop forever. I suppose that's incorrect 🤔

#RISCV "Wait for Interrupt instruction (WFI) provides a hint to the implementation that the current hart can be stalled until an interrupt ... so a legal implementation is to simply implement WFI as a NOP" 🤔
